WlNDOW-SASH BALANCE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

A mplication filed July 27.1905. Serial No. 271,496.

To all whmn it may concern:

Be it known that 1, JOHN G. HALL, a citizen of the United States, residing at New Providence,. in the county of Lancaster and State of Pennsylvania, have invented a new and useful Window-Sash Balance; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to windows, and has for its object to provide a cordless weight for window-sashes which will hold a windowsash in any desired osition and which pro vides means for firm y locking the weight at the desired point, which in turn locks the window.

Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claim.

My invention is illustrated in the accompanying drawings, which, with the figures of reference marked thereon, form a part of this application, and in which drawings Figure 1 is a longitudinal section through a window-frame, showing the upper and lower sashes and the means for counterbalancing and locking the same. Fig. 2 is a detail perspective fragmental view of a portion of one of the sashes and part of the frame, showing the ratchet-wheel and ratchet-bars and the locking device for the weighted member; and Fig. 3 1s a sectional View through the locking device.

Reference now being had to the details of the drawings by figure, 1 designates the framework of a window, having mounted therein the usual lower and upper sashes 2 and 3, respectively. Mounted upon one side of the lower sash 2, as at 4, is a suitable rackbar 5, which is adapted to engage a suitable pinion 6, which is rotatably mounted upon a pin 7, which is mounted in the framework 1. This pinion is adapted to engage a suitable rack-bar 8, which is bolted or otherwise secured to a weighted member 9, which has longitudinally-vertical movement within the framework of the window 1. A plurality of perforations 10 is provided in a metallic bar 11, which is screwed or otherwise secured to the side of the weighted member 9, and adapted to engage said perforations is a suitable spring-pressed pin 12, which is mounted within the outer portion of the framework of the window. This pin 12 is provided with a suitable flange 13, which is adapted to have a s ring 14 to bear against the upper surface tliereof, the other end of said spring being adapted to bear against the under surface of a plate 15, bolted or otherwise secured to the outside of the framework of the window. Said spring-pressed pin 12 is provided with a suitable recess 16, which is adapted to engage therewith a suitable spring-pressed bolt 17, which is mounted within a suitable metallic casing, which is screwed or otherwise secured to the outside of the framework.

Mounted upon one side of the upper sash 3, as at 18, is a suitable rack-bar 19, which is adapted to engage a suitable pinion 20, which is rotatably mounted upon a pin 21, which is mounted in the framework 1. Said pinion is adapted to engage a suitable rack-bar 22, which is bolted or otherwise secured to a weighted member 23, which has longitudinally-vertical movement within the framework of the window 1. A plurality of perforations 24 is provided in a metallic bar 25, which is screwed or otherwise secured to the side of the weighted member 23, and adapted to engage said perforations is a suitable spring-pressed pm 26, which is mounted within the outer portion of the framework of the window. Said pin 26 is provided with a suitable flange 27, which is adapted to have a spring 28 to bear against the upper surface thereof, the other end of said spring being adapted to bear against the under surface of a plate 29, bolted or otherwise secured to the outside of the framework of the window. Said spring-pressed pin 26 is provided with a suitable recess 30, which is adapted to engage therewith a suitable spring-pressed bolt 31, which is mounted within a suitable metallic casing, which is screwed or otherwise secured to the outside of the framework. Thus by referring to Fig. 3 of the accompanying drawings, in connection with the detailed description of the same, as hereinbefore given, it will be readily understood how a sash is locked in any desired position.

From the foregoing it will be observed that by the provision of the apparatus shown and described a simple and efficient means is provided for locking either the upper or lower sash of a window in a closed position or in any desired open position.

Having thus fully described my invention,
